1. General SGF FF Example File
The example SGF file and the GIF pictures should illustrate some of the
features of SGF FF and give application coders an impression how to draw
or represent various properties.
Note: The colors chosen, the screen structure (seperate window for
variations & other information, seperate comment window) etc. are specific
to Primiview, the application used to create these pictures.
Your application doesn't have to look the same.
You are free to choose whatever colors, structures etc. you want.
Same goes for representation of advanced markup such as DD (dimmed points).
Primiview's node numbering starts with zero (0) (just like MGT).
Node numbering is done in the order the nodes appear in the SGF file.
If your application can't handle SGF collections then you have to extract
the second part using a split utility or a text editor.
Gametree 1: properties
Variation A: (Moves, comments, annotations)
There's nothing special about these nodes.
Note the new (FF) way to write pass moves: "B", "W" (nodes 12, 13)
Variation B: (Setup)
This variation illustrates how to use AB, AW, AE & PL.
Here compressed point lists are used for the first time.
Have a look at the SGF specification and the two pictures to get the idea.
Variation C: (Markup)
Node 19 shows various kind of board markup.
Node 20 shows labels. Label length are from 1-8 chars.
There are two pictures: the second one shows different ways of handling
Node 21 shows three new FF properties: DD (dimmed points),
AR (arrows) and LN (lines)
The picture ex08.gif illustartes how VW (view) works.
The VW property isn't directly encoded into the SGF file.
The picture shows node 19 and gives two examples of a restricted view.
Variation D: (Style & text type)
Node 22 contains a comment text which serves as example for hard and
soft linebreaks and for different encodings of linebreaks.
- Nodes: 22-32
- ex09.gif: ST (children / no board markup) (node 23)
- ex10.gif: ST (siblings / auto-board markup) (node 23)
Note that ex09.gif & ex10.gif are both taken from the same node (#23).
They only differ in the ST (style) used. The example itself doesn't contain
a ST property. The picture just illustrates the use of ST.
Variation E: (Time limits, captures & move numbers)
This variation shows the use of BL, WL, OB, OW, MN.
It also contains a suicidal move (and capture).
Gametree 2: Game-info
This game-tree shows how game-info properties may be stored, if there are
several games merged into a single gametree. See the comment texts for
what the game-info should look like.
2. Print Example Files
SGF provides some properties for storing print and layout information.
These properties are: FG, VW, PM and MN.
The following files contain two games from GoWorld 78 (of course, the commentary isn't
included, but all the board-markup is). You should have this magazine to
verify the layout with the example files.
